4 4 System Owner s Manual 1. Tigo Energy Maximizer TM System The Tigo Energy System (Fig.1) is a perfect enhancement to a well-designed solar array. The Tigo Energy Maximizer System improves energy harvest by maximizing each module independently, provides module-level operation and maintenance (O&M), and enables the PV-Safe feature to disconnect the array at the module level. The Tigo Energy Maximizer System includes a Module Maximizer installed on the back of every solar module or Dual Maximizer installed on the back of every other solar module. It also includes a Maximizer Management Unit (MMU) which is typically wall-mounted near the inverter. The MMU features an LCD display showing the system status, and also has a button to activate PV-Safe. Finally, the system includes the MaxiManager Software to view the array s performance from anywhere. This owner s manual will help you get the most out of your Tigo Energy System, explaining key features of the software, as well as how to activate and test the safety features.

Tigo Energy PV-Safe TM Feature LCD display PV-Safe button MENU button ENTER button DOWN button UP button Fig Tigo Energy Maximizer Management Unit (MMU) When inspecting your installation, check the front panel of the Tigo Energy Maximizer Management Unit (MMU) for the Tigo Energy PV-Safe button. This is an indication that the system is equipped with the advanced safety feature. The Tigo Energy PV-Safe feature provides the ability to deenergize your solar array at the module, so there are no highvoltage wires running down from the array. This should be used in emergency and maintenance situations. By pressing the PV-Safe button on the Management Unit, the Tigo Energy Module Maximizers will attempt to stop voltage from passing to the PV wiring between the Module Maximizer and the inverter. If the Maximizer Management Unit does not have access to AC power or is otherwise impaired, the PV-Safe function will not be able to be initiated from the PV-Safe button on the MMU. However, a system configured with the Tigo Energy Maximizer solution will attempt to enter the PV-Safe mode automatically when the AC is disconnected at the building main breaker. Once PV-Safe is activated, confirm that the modules are disabled on the Management Unit display, on the Summary page of the web-based software tool, or by testing the DC lines with a voltmeter. When the PV-Safe button is activated, the MMU will display PV-SAFE PRESSED and Requesting... to indicate the command has been sent to the Maximizers. As the Maximizers are responding, the MMU display will indicate how many have successfully disconnected (example: Resp: 15/48 ). Once the system successfully receives acknowledgement from all of the Module Maximizers in the array, the MMU will display RESPONDING. Should the MMU not receive proper response from one or more of the Module Maximizers or communication has been lost, the display will read NOT RESPONDING. If the NOT RESPONDING message is present, the system owner must assume that the system is still active and voltage is present as in a standard PV array. Always inspect the system prior to re-energizing the modules. Returning the modules to the ON state may only be done from the MMU console. Ensure the MMU is properly powered and the inverter is in the ON position. Lift the protective cover on the MMU and press the MENU button, then press ENTER. Use the down arrow to select 2. CONTROL, then press ENTER. Scroll down to 2.1. PANELS ON, then press ENTER. Press ENTER again to confirm. Ensure the inverter is receiving DC voltage. While PV-Safe is meant to enhance system safety, care should always be exercised to avoid high voltage DC wiring regardless of whether the PV-Safe function is enabled. Tigo Energy cannot guarantee complete deactivation of the array when the PV-Safe button is pressed. Tigo Energy PV-Safe must be tested as part of the installation process, and should be routinely tested on an annual basis. 2. PV-Safe

6 6 System Owner s Manual 3. Tigo Energy MaxiManager TM Software The Tigo Energy MaxiManager software manages arrays of all sizes to give system owners unprecedented visibility of every module. System owners are alerted to actionable information so that they can manage their system based on pre-set parameters. System analytics track performance relative to expectations and proactively suggest maintenance actions to keep the system operating at maximum production and uptime. 3.2 My Installations Page The My Installations page provides a set of summary tools to monitor the performance of your array(s). The fields include Dashboard, System Map, and Kiosk view. There is also a System List which you can use to navigate to a systemspecific view Log In To manage and view your system, please open your web browser and navigate to: In the upper right hand corner of the home page, click the Login link to go to the Login screen. Please enter the login and password that was provided to you by your installer. Dashboard The Dashboard view provides summary statistics such as total energy production, carbon offset, aggregated peak power, or number of installations. You can also see these statistics on any time frame including lifetime, year-to-date or a specific date (Fig. 4). System Map The System Map shows the physical location of each site. The satellite view of the installation can help you better understand orientation, shade and system lay-out with Google Map integration (Fig. 4). System List From here, select the installation that you would like to access by clicking the project name of the system (Fig. 4). Fig Login Page Login information provided by your installer Kiosk View Looking for a way to show off your system on a TV screen or lobby? The Tigo Energy Kiosk View enables an easy-tounderstand slideshow with a variety of images & graphs that showcase your system s performance.

8 8 System Owner s Manual 3.3 Summary Page Once you ve clicked the system that you would like to access, you will be taken to the Summary page. This screen shows real-time and historic power production from each module of your array. The color of each PV module indicates a comparative measurement of power generated among modules (brightest indicates most power production). This is particularly useful for finding anomalies such as shading. The number displayed inside each module is the instantaneous power measured at the time indicated in the Data Navigator (lower left corner of the Summary page). These numbers are also meaningfully colored. The text on a panel will be yellow if the module s power is less than 90% of the expected production. It s red if the power is less than 75%. When placing the cursor over a module, the program automatically highlights all modules on the same string, along with its corresponding inverter. When the cursor is over the inverter, all strings attached to that inverter are highlighted. Note: If different module types are used in the solar array, their max voltage will be displayed on the bottom right corner of each individual module Large System For arrays with 300 or more modules, the view is displayed at a string level first. The same color scheme and definitions described above apply to the string shapes. The border of the string is colored to indicate if there are any underperforming modules in that string. The presence of one panel operating under 90% of the maximum will result in a yellow border; less than 75% results in a red border.to view the panel level detail of the array, simply zoom in on the system map via the Zoom Control or using the mouse wheel. You may also double click directly on the area you d like to see. If the system includes an optional light sensor, the sun intensity (irradiance, measured in Watts per square meter - W/m 2 ) is indicated in the upper right hand corner above the modules. Similarly, if the system is equipped with temperature sensors, the ambient or module temperature (depending on the placement of the sensor) will be displayed next to the small thermometer icon. The Summary view goes into auto-updating mode after 30 minutes of inactivity. Until the system is interrupted, the view will refresh itself every 10 minutes thereafter. Note: If the module placement does not represent the physical layout of your array, see section This section will provide instructions on how to move the modules and inverters on the Summary Page to more accurately reflect the actual layout of the PV array.
